[Paraview] What part of the pipeline is producing the request for UPDATE_EXTENT?

[Mike Jackson]

I was under the impression that I needed to set the UPDATE_EXTENT  
like the following in my RequestInformation() method:

outInfo->Set( vtkStreamingDemandDrivenPipeline::UPDATE_EXTENT(), this- 
 >DataExtent, 6 );

but I think that is a bad assumption for a reader. Is the ParaView  
pipeline actually setting the UPDATE_EXTENT based on what it needs to  
render?
